HOPPER.

, SPECIFICATION forming part of Letters Application filed October 29, 1903.

To all whom it may concern.-

Be it known that I, Norris F. PALMER, a'citi-. zen of the United States, residing at New York city,i.(Brooklyn,) county of Kings, .and State. 5 of New'York, have invented new and useful. .Improvements in Hoppers, of which the fol-' lowing is aspecification,

This invention relates to ahopper more especially designed for 'molds adapted for the I manufacture of artificial stones and for similar purposes.

Myimprovedhopper can be readily manipulated and greatly facilitates the charging of the mold as well a's the striking 0E of the I green block.

In the'accompanying drawings, Figure 1 is a longitudinal section, partly in elevation, of my improved hopper, showing it lowered; Fig. 2, a similar view. partly brokenflaway, 2 showing the partsin a different-position; Fig. 3, a side view of the hopper, showing it raised with the mold in section; Fig. 4, an enlarged cross-section on line 4 4, Fig. 2.; Fig.5, an end view of the hopper; and Fig. 6,'an enlarged cross-section on line 6 6, Fig. I.

The hopper proper is composed of two inclined sideplates a and an inclined front plate a, while its back is open. Angle-irons 0 connect the sides a to the front a and are attached at the open backto atransverse bar a? The angle-irons a are bent outwardly, and-upwardly at the top, as at a to accom modate a pair of rails I), which are secured to the angle-irons by screws 6 or otherwise. At 35, their lower ends the angle-irons a terminate in stepped projections Fig. 3, which engage the similarly-stepped upper edge 0 of the mold 0. This mold has preferably hinged or movable sides, which are thus locked by the hopper against spreading or opening at the corners when the concrete is being tamped. The rails b are of a length to extend beyond both sides of the hopper proper and are hinged at their lower or left-hand ends 6 45 Fig. 3, to a suitable support or frame d. At their upper ends the rails b are connected to a counterweight e by a rope e, running-over pulleys f. When the rails b are swung up, Fig. 3, they, together with the hopper, will 5 be sustained in a vertical position by means rives over the hopper.

of the counterweight. When the rails are lowered into a horizontal position, Fig. 1, the hopper will be set squarely upon the mold, to which it will become locked by a springcatch g. per may be readily fitted to the mold while the latter is to be filled and may as readily be removed while the mold is opened and the green block is removed. c

. Upon the rails b is free to slide a cut-off box 9 h, guided along the rails by flanges h, that'engage corresponding grooves of the rails. The box h may travel to and fro within the hopper and when not in use may be pushed through the open back of the latter and upon the 5 right-hand extension of the rails b, so as to clear the hopper, Fig. 1. The box is open at its front or inner side and is here provided with-an inclined downwardly-extending knife or blade H, which is adapted to strike/off the 7 green block. Thus when the box is moved toward the left the knife will cut oil the block and the cut-01f upper stratum will pushed into the box.

d is a filling-box, which is also slidable on the rails b and is held thereto by the flanges 11. This box is free to be moved to and fro along the rails above the hopper and when out of use may be pushed upon the left-hand ends of the rails b. The rails 6 connect at their left end with a fixed track jof frame (Z, so'that the box 41 may be readily transferred from the rails Z) upon the track ,7'. The box e' is provided with a center partition 2'' and with a double trap-bottom, the two sections 71 of which are hinged to the box at a d istance above its open lower end, as at 5. Thus when the trap-bottom is opened the contents of the box'will be dumped into the ho'pper. When the trap is closed, its sections 6 9 are locked in a horizontalposition by suitable catches i The operation of the device will be readily understood. The box 2', standing upon the track j, is filled with concrete. The hopper is swung down to engage the mold and the box 71 is pushed u'ponandalong the rails 6 until it ar- The trap-bottom i is now opened to dump the concrete through the hopper into the mold, after whichthe box is Thus it will be seen that the hop- 55 l .1 -i l g the pit ready to be shoveled into the box 71 for the next block.

It Will be seen that my improved hopper can be quickly manipulated and that it provides means for readily charging the mold and returning the surplus to the dump. In this Way the operation of molding the block is greatly accelerated, while cleanliness is insured and Waste is avoided.

What I claim is 1. The combination of a hopper with a cutofi box movable Within the hopper, and with a cutter depending from the box,su bstantially as specified.

2. The combination of a hopper having an open back with a pair of rails projecting beyond the same, a cut-off box movable along the rails, and a cutter depending from the box, substantially as specified.

3. The combination of a hopper with a filling-box movable above the hopper, and wit] atrap-bottom in the filling-box, substantiall; as specified.

4. The combination of a hopper with a pai of hinged rails projecting beyond the same, fixed track adapted to connect with thesai rails, and a filling-box having a trap-bottom and movable along the rails, substantially a specified.

5. The combination of a pair of rails with: hopper carried thereby and with a cut-off b0: and a filling-box movable along said rails, sub stantially as specified.

6. The combination of a pair of rails with hopper carried thereby and having an opei back, a cut-ofi box having a depending'cutter and a filling-box having a trap-bottom, thy cut-ofl box and filling-box being movable along the'rails, substantially as specified.
